Kratos Defense & Security Solutions, Inc. and RTX Corporation Stock Value Grades

Company	Ticker	Value
Kratos Defense & Security Solutions, Inc.	KTOS	F
RTX Corporation	RTX	F

Successful stock investing involves buying low and selling high, so stock valuation is an important consideration for stock selection.

Buying stocks that are going to go up typically means buying stocks that are undervalued in the first place, although momentum investors may argue that point.

AAII’s A+ Investor Value Grade derives from a stock’s value score. The Value Score is the percentile rank of the average of the percentile ranks of the price-to-sales ratio, price-earnings ratio, enterprise-value-to-EBITDA (EV/EBITDA) ratio, shareholder yield, price-to-book-value ratio and price-to-free-cash-flow ratio. The score is variable, meaning it can consider all six ratios or, should any of the six ratios not be valid, the remaining ratios that are valid. To be assigned a Value Score, stocks must have a valid (non-null) ratio and corresponding ranking for at least two of the six valuation ratios.

Stocks with a Value Score from 81 to 100 are considered deep value, those with a score between 61 and 80 are a good value and so on.

Kratos Defense & Security Solutions, Inc. has a Value Score of 2, which is Ultra Expensive. RTX Corporation has a Value Score of 20, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Neither Kratos Defense & Security Solutions, Inc. or RTX Corporation has a high enough value grade to be considered a “winner.” Investors who are considering these companies should do additional due diligence and research to see if either could be a good addition to their portfolio. It’s important to look at a wide range of financial metrics in order to determine if Kratos Defense & Security Solutions, Inc. or RTX Corporation is the better investment when it comes to value.

Kratos Defense & Security Solutions, Inc. and RTX Corporation Growth Grades

Company	Ticker	Growth
Kratos Defense & Security Solutions, Inc.	KTOS	C
RTX Corporation	RTX	A

The foundation of growth investing is seeking out stocks of companies exhibiting strong, consistent and prolonged growth that is expected to continue into the future.

In order to compute the growth score and assign it a letter grade, the percentile ranks for each of three components‐consistency of annual sales growth, five-year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations‐must be determined. These three rank figures are added together, and the sum is ranked against the entire stock universe to arrive at a company’s Growth Score to create an equal distribution of grades.

The companies in the bottom 20% of the stock universe receive Growth Grades of F, considered to be very weak, while those in the top 20% receive A grades, which are considered very strong.

Kratos Defense & Security Solutions, Inc. has a Growth Score of 56, which is Average. RTX Corporation has a Growth Score of 100, which is Very Strong.

The Growth Grade Winner: RTX Corporation

As you can clearly see from the Growth Grade breakdown above, RTX Corporation has a more attractive growth grade than Kratos Defense & Security Solutions, Inc.. For investors who focus solely on how a company is growing relative to other companies in the same industry, RTX Corporation could be a good stock to add to their portfolio. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Kratos Defense & Security Solutions, Inc. and RTX Corporation’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Kratos Defense & Security Solutions, Inc.	KTOS	B
RTX Corporation	RTX	B

Earnings estimate revisions scores consider the magnitude of a company’s earnings surprise in its last two reported fiscal quarters. Often, positive surprises beget further positive surprises‐or at least continued sales growth (the exact opposite is generally true, too).

Estimate revisions offer an indication of what analysts are thinking about the short-term prospects of a firm. Estimate revisions are based on the statistical significance of a firm’s last two quarterly earnings surprises and the percentage change in its consensus estimate for the current fiscal year over the past month and past three months.

Kratos Defense & Security Solutions, Inc. has a Earnings Estimate Score of 61, which is Positive. RTX Corporation has a Earnings Estimate Score of 73, which is Positive.

The Earnings Estimate Revisions Grade Winner: It’s a Tie!

Looking at the Earnings Estimate Revisions Grade breakdown above, both Kratos Defense & Security Solutions, Inc. and RTX Corporation have a grade of B. For those focusing solely on a company’s estimate revisions, other financial metrics will need to be evaluated to determine whether Kratos Defense & Security Solutions, Inc. or RTX Corporation is a better fit.

Other Kratos Defense & Security Solutions, Inc. and RTX Corporation Grades

In addition to Estimate Revisions, Growth and Value, A+ Investor also provides grades for Momentum and Quality.

Momentum grades help uncover stocks experiencing anomalously high rates of return; research finds that stocks with high relative levels of momentum tend to outperform, whereas those with low levels of momentum tend to continue underperforming.

AAII’s A+ Investor Quality Grade comes from the ranking of key metrics.
